, Be it known that we', JOHN S. Manin and HENRYA. SGHELEMAN, both4citizens of the United States, residing in the clty and 5. county ofPhiladelphia, State of jPennsylf van ia have ,inyentedfa new and usefulAux- ;iliary Water-Heater," of which the followy ing isaspeciication y l",Oiixminvention' consists of an improved D wateryfheater,,yparticularly adapted to be supported within `the fire-pot or ,combustion...chamber of 'la furnace, stove or gas heater. .It further consists ofa heatingchamber having radiating hollow branches to proi vide -a largeheating surface.

It further consists ofa heating chamber having a water feed pipeenteringfrom above lthrough `thetop of thesaine and sur,-

- rounded by the discharge-pipe.' p

i It further consists of a heating'chamber having a water feed pipeentering it from above through the top of the same and`extending intov apipe extension.

-Itfurther -consists of other novel feai tures of construction, all aswill be hereinafter fully set forth.-

For the purpose of illustrating our'invention, we have` shown in theaccompanying ldrawings a preferredembodiment therel of which is atpresent preferred by us, since vthe same has been found yin practice togive satisfactory and reliable results, although it is to be understood'that the various 1nstrumentalities of which-our invention con- `-Eistscan be variously arranged and organized and that our invention is notlimited to the precise arrangement and organization of theseinstrumentalities as herein shown and described. v

erably of cast metal, formed with radiating hollow branches, 11, makinit substantially star-shaped, and also ormed at its top and bottom withinternally threaded central nipples, 2 and 3, respectively. A pipe, 4,is screwed into the upper nipple 2, and having a coupling, 5, screwedupon its upper end, which coupling has a lateral nipple, 6, into whichmay be screwed a pipe for conveying the heated Water.v A sup lypipe, 7,1s axially secured in said coup ing and extends axially through the hotwater discharge pipe 4, down to about the middle of the water-heatingchamber, where a disk or baiilelate, 8, surrounds the same and has its eges integral with or closely fitted against the junction points yof thesides of the radiating branches of the chamber. The bottom opening ofthe heating-chamber is closed by a plug, 9. If it is desired to extendthe heating surface of the chamber, a pipe or waterle ,'10, may besecured into the bottom `nippe of said chamber to extend fartherdowninto the fire-pot o'r com' bustion chamber, and the lower end ofsaid pipe is closed by the plug 9. When the heater is provided with thewater-leg, the supply-pipe is extendedto near the lower end of thelatter.

In Fig. 4, the heater is illustrated in place in a furnace, the stove ofwhich is indicated by the numeral 12, and between which stove and thejacket, 13, the heating chamber, 14, is formed. The discharge-pipe 4 issuspended by a coupling, 15, or similar means resting upon the edge ofan opening in the top of the stove.

As cold water'enters from above, it is warmed by passing through thehollow column of hot water ascendin on the outside of the supply-pipe 7throng the dischargepipe 4 and thereupon such water enters the heatingchamber at the hottest point, at or below the bottom of the same, whereit is directed outwardly b the radiating brano es of said c amber, beingheated, whereupon the heated 4water asce ds in hollow celu/Inn tirou'ghthe dischCyZge-pipe to a boiler or whatever d stinati n may be providedfor it. If /the'lizatin chamber is placed some distance above th normalsurface of the fueledaud it is de'L sired to provide additional heatingsurfac, the downwardly extending tube or wate leg, illustrated in Fig.2, is employed and addi'fgnal heatin ofthe water-in such water-leg isattaine in the fuel-bed.

It is evident that one or more heatingchambers may b e placed in agas-heater or connected 'in a larger pipe so asl to be sur- Vrounded bysteamer smoke as Well as in l the fire-pot or combustion-chamber of afur- --nace orfstove burning solid fuel. 10

n heating-chamber from above, the Water in Byproviding vthe inlet-pipeentering the said pipe will be preheated before entering such chamber,and there will be no interference by the heater with the tir pot orcomi' of the supply-pipe will pass around the edge I '.tortuous channelsfor the Water so as to expose the same to the heat for a comparativelylong space of time, and the star-shape of the chamber will provide alarge heating surface. f

Having thus described our invent-ion,

what We claim as new and desire to secure p by Letters Patent, is

1. In a device of the character stated, a

vheating-chamber, a .discharge-pipe extending from the top of the same,a supply-pipe projecting axially through said dischargepipe into theinterior of said chamber, and a baille-plate secured to surround saidsupplypipe above the lower end of the same. V 3 2. In a device of thecharacter stated, a heating chamber having radiating branches, abaille-plate within `sald chamber and having its edges extending to thejunction points of the Walls of the radiating branches 4 of the chamber,a discharge-pipe extending from the top of the chamber, and a supplypipeprojecting axially through the discharge-pipe and opening below saidbaille'- plate. 4

. 3. In a device of the character stated, a heating-chamber havingradiating branches, a discharge-pipe extending from the top of saidchamber, a supply-pipe extending axially through said discharge-pipe andinto 5 the chamber, a baille-plate surrounding said supply-pipe abovgthelower end of the same, and a Water-leg extending from the bottom of theheating chamber.
